4.      Split up the harmonic motion 8 sin (ωt + π/4) into two harmonic motions one of which has amplitude of 10 and phase difference zero.

5.      A steel shaft 6 cm diameter and 50 cm long fixed at one end carries a flywheel of weight of 1000 kgf and radius of gyration 30cm at its free end. Find the frequency of free longitudinal transverse and torsional vibration E= 2 x 106 kgf/ cm2, C = 3.8 x 106 kgf/ cm2.

6.      A shock absorber is to be designed so that its overshoot is 10% of the initial displacement when released. Determine the damping factor. If the damping factor is reduced to one half this values, what will be the overshoot?

7.      Why do we consider natural frequency in vibration?

8.      A simple U tube manometer filled with liquid is ahown in figure 3. Calculate the frequency of resulting motion if the minimum length of a manometer tube is 0.15m.

Assignmnet No III ---- Machine Design II


 

Assignment No III
Machine Design - II
Topic: Design of Belt, Rope, Chain, Clutch, Brakes, Bearing, lubrication system and CAD


Date of issue: 9th March, 2012                                       Last date of Submission: 23rd March, 2012


1.      It is required to select a flat-belt drive for a compressor running at 720 rpm, which is driven by a 25 kW, 1440 rpm motor. Space is available for a centre distance of 3m. The belt is open type.

2.      Design a dry single plate friction clutch for following data:
P = 25 kW, N = 1440 rpm, Mean radius = 5 x face.

3.      Select a suitable chain drive to transmit 30 kW from an electric motor running at 1200 rpm to a line shaft running at 250 rpm. Motor shaft diameter is 60 mm and the centre distance is approximately 600 mm. Service is l0 hr/day, 6 days a week. Good lubrication condition is expected.

4.      A band brake has to absorb 4.5 k W at 150 rpm. For long life, the maximum pressure between lining and drum is 0.7MPa. The width of band is 50 mm and μ = 0.12. Find the angle of wrap if the brake drum diameter is 300 mm.

5.      A tentative design of a journal bearing result in a diameter of 75 mm and a length of 125 mm for supporting a load of 20 kN. The shaft runs at 1000 r.p.m. The bearing surface temperature is not to exceed75°C in a room temperature of 35°C. The oil used has an absolute viscosity of 0.01kg/m-s at the operating temperature. Determine the amount of artificial cooling required in watts. Assume d/c = 1000.

6.      Discuss the design procedure of lubrication system in transmission system.

7.      Describe the detail design process for computer aided design. Discuss how use of computers assist a designer in each stage of the design process with respect to reducing the time and providing wider spectrum to design solutions.
